Description
Miguel Ángel López Carrillo's team devised a way to measure the enantiomeric purity of sorted carbon nanotubes absolutely, without needing pure reference samples that do not exist. Chiroptical spectroscopy reads purity quickly and without damage, but calibrating it for single-walled nanotubes had been blocked by the lack of enantiopure standards.
Counting thousands of individual tubes by hyperspectral fluorescence imaging let them anchor ensemble circular dichroism and Raman optical activity signals to true purity, yielding universal calibration curves from the purest samples. The method extends to other tube chiralities and could make chirality sorting quantitative rather than approximate.
